fix(docs): stop the documentation toolchain from emitting warnings

apidoc now excludes roles/ and library/ the way it already excluded tests/.
A role name carries hyphens and is therefore not an importable module path,
so automodule reported 44 invalid signatures and rendered nothing; library/
holds ansible modules whose ansible.module_utils imports exist only inside a
play. Measured: 168 generated pages drop to 151, and the 17 that go consist
of a heading and automodule directives on unresolvable paths.

The role page generator fits every section underline to its title. pandoc
counts one character fewer than docutils where a heading ends in a stray
variation selector left behind by a removed emoji. It also escapes inline
markup in role metadata, because one description reads (*.parent) and opened
an emphasis that never closed.

The index generator underlined a 21-character caption with 19 characters.

conf.py adds the tel scheme, without which the phone number in SECURITY.md
is an unresolvable reference, and the extract copies the image assets into
its conf directory the way the site builder does, without which every run
reports a missing html_static_path and favicon.

Four tests pinned values this changes. The fifth, the extension count in
test_conf, asserted nothing the loop below it does not already prove and
broke on every legitimate addition; it now asserts the list is non-empty, so
that loop cannot run over nothing.

With this, make i18n-extract domain=docs finishes with zero warnings under
the -W gate.
